摘要:
An apparatus for storing fluid and dispensing multiple portions of the stored fluid has a container defining a variable-volume storage chamber; a dispensing valve including a valve inlet coupled in fluid communication with the variable-volume storage chamber, and an elastic valve member in fluid communication with the valve inlet and defining a normally-closed valve opening; a manually engageable actuator; and a pump including a compressible member defining a compression chamber coupled in fluid communication with the variable-volume storage chamber. Multiple portions of the stored fluid are hermetically sealed in the variable-volume storage chamber. The actuator is manually engageable and movable between (i) a first position wherein the compression chamber defines a first volume, and (ii) a second position wherein the compression chamber defines a second volume less than the first volume. In the second position the fluid in the compression chamber exceeds a valve opening pressure and, in turn, moves the elastic valve member between (i) a normally closed position hermetically sealing the one-way valve and variable-volume storage chamber with respect to ambient atmosphere, and (ii) an open position permitting fluid flow through the valve opening.
摘要:
A dispenser for dispensing a substance, such as a pharmaceutical, ophthalmic, dermatological, cosmeceutical, cosmetic or other product, has a body with a variable-volume storage chamber for storing the product. A dispensing portion of the dispenser is connected with the body and has a compression chamber in fluid communication with the storage chamber for receiving substance therefrom, and an outlet aperture coupled in fluid communication with the compression chamber. A one-way valve of the dispenser includes an axially-extending valve seat and an axially-extending flexible valve cover seated on the valve seat and defining a normally-closed, axially-extending seam therebetween forming a fluid-tight seal between the valve cover and valve seat. The flexible valve cover is movable relative to the valve seat and the seam is connectable in fluid communication with the outlet aperture to allow the passage of substance through the seam and out of the dispenser. The dispenser further comprises a manually-engageable actuator connected to the dispensing portion movable between first and second positions to dispense substance within the compression chamber through the outlet aperture, and an integral, dome-shaped spring for biasing the actuator in a direction from one of the first and second positions toward the other.

An apparatus for storing fluid and dispensing multiple portions of a stored fluid therefrom. The apparatus comprises a container defining a variable-volume storage chamber for receiving therein the fluid and a dispensing valve including a valve inlet coupled in fluid communication with the variable volume storage chamber, and a valve member in fluid communication with the valve inlet and defining a normally-closed valve opening. The valve member is responsive to fluid at the valve inlet exceeding a valve opening pressure to move between (i) a normally closed position, and (ii) an open position permitting fluid flow through the valve opening. The dispensing valve defines a dispensing axis defining a direction substantially along which fluid is dispensed from the valve, and further includes an outlet surface over which dispensed fluid flows oriented at an acute angle relative to the dispensing axis for preventing the collection of residual dispensed fluid thereon.

A translation device includes a receiver, a processor and a transmitter. The receiver is configured to receive packets from a first party designated for a second party, the received packets including parameters associated with the first party. The processor is configured to translate the parameters of the received packets to form translated packets such that the parameters of the translated packets are associated with the device. The transmitter is configured to transmit the translated packets to the second party.

A method for starting up the communication device includes searching a non-volatile storage unit of the communication device for start up data of the communication device according to a predetermined identifier of the start up data, loading the start up data into a volatile storage unit of the communication device, starting the communication device according to the start up data in the volatile storage unit. The method also includes searching the non-volatile storage unit for data except for the start up data, load the data except for the start up data into the volatile storage unit.

A separation column for use in a separation process such as chromatography, electrochromatography and electrophoresis is described. The separation column includes multiple collocated monolith support structures and interconnected channels defined by the support structures. The monolith support structures and interconnected channels are created on a substrate using an isotropic etching. The separation column also includes a cover plate disposed on the etched surface of the substrate, creating an enclosed separation column.
